The Ecological Indicator Values for Europe (EIVE) 1.0 were released in January 2023 and are the hitherto most comprehensive ecological indicator value (EIV) system for Europe. They comprise the assessment of the five main niche dimensions (moisture, nitrogen, reaction, light, temperature) for almost 15,000 vascular plant taxa. EIVE was constructed...

Biological invasions are one of the main threats to biodiversity, but they also offer insights on different ecological processes, as highlighted by the hypotheses posited to explain the phenomenon. We explore the relative importance of different hypotheses using biotic (native diversity) and abiotic factors (climate and landscape configuration) as...

Aims: To develop a consistent ecological indicator value system for Europe for five of the main plant niche dimensions: soil moisture (M), soil nitrogen (N), soil reaction (R), light (L) and temperature (T). Study area: Europe (and closely adjacent regions). Methods: We identified 31 indicator value systems for vascular plants in Europe that contai...

The heterotypic synonyms Verbascum limnense and Celsia tomentosa are neotypified and lectotypified, respectively, and their nomenclature is clarified. The former binomial represents the correct name at species rank for a range-restricted, paleoendemic plant confined to Central Greece. Furthermore, the new nothospecies Verbascum × sipiadense, repres...

Human-induced climate- and land-use change have been affecting biogeographical and biodiversity patterns for the past two centuries all over the globe, resulting in increased extinction and biotic homogenization rates. High mountain ecosystems are more sensitive to these changes, which have led to physiological and phenological shifts, as well as t...

Greece, as one of the European biodiversity hotspots, is long since in the focus of botanical investigations. Among historical researchers significantly contributing to the floristic and taxonomic exploration was Eugen von Halácsy, a Viennese physician and botanist.

Ruderal plant species typically occur and prevail in frequently disturbed areas especially in sites with pronounced direct or indirect human activity. In Greece ruderal taxa (both exclusive and non-exclusive) account for 23.9% of all recorded plant taxa. This study presents an analysis of the ruderal plant diversity patterns in the 13 floristic reg...

Aims: Syntaxonomic classification is widely used for vegetation survey in Europe. The long history of its use has produced many concepts and names of vegetation units that need to be revised and integrated into a single classification system. Here we (1) present a new, global hierarchical syntaxonomic systems of alliances, orders, classes of the Br...

Background: Ecological indicator values (EIVs) have a long tradition in vegetation ecological research in Europe. EIVs characterise the ecological optimum of species along major environmental gradients using ordinal scales. Calculating mean indicator values per plot is an effective way of bioindication. Following first systems in Russia and Central...

Asperula tymphaea T. Gregor, Meierott & Raus is described as new to science and is compared to the sympatric A. aristata subsp. thessala (Boiss. & Heldr.) Hayek. The new species inhabits high-mountain calcareous screes and so far appears to be endemic to Mt Timfi (NW Greece), although its total range needs to be studied.

Background: Speciose clades usually harbor species with a broad spectrum of adaptive strategies and complex distribution patterns, and thus constitute ideal systems to disentangle biotic and abiotic causes underlying species diversification. The delimitation of such study systems to test evolutionary hypotheses is difficult because they often rely...
